Ashton Eaton is back in business. The US all-rounder had problems with his high jumping in Moscow at the 2013 World Championships because of a hamstring injury, but those problems are long gone.

Russia s Yekaterina Koneva won a modest contest with the shortest winning mark since the event was formally introduced onto the competition programme at the 1993 World Indoor Championships.

Ryan Whiting extended the US domination of the men s shot put at the IAAF World Indoor Championships by clinching victory for the USA for the sixth successive edition of the championships, successfully defending the title he won two years ago in Istanbul.

Sweden s Abeba Aregawi fulfilled her role as the prohibitive favourite for the women s 1500m as she ran away from the rest of the field at 500m and just carried on extending her lead throughout the rest of the race before crossing the line in 4:00.61.

Having come to the IAAF World Indoor Championships in Sopot with the best distance of the winter under his belt, Ryan Whiting felt the pressure to live up to the mantle of being the favourite for the men s shot put gold medal.

USA s Francena McCorory lived up expectations as the favourite, speeding to a popular victory in 51.12.
